The International Research Group on Immuno-Scintigraphy and Therapy (IRIST) is an initiative of European investigators that aims to stimulate and intensify the international interaction and collaboration between investigators working in the field of radionuclide targeting of malignancies.
IRIST was founded in 1986 by different European leading groups, including the group of Prof. Keith Britton (London, UK), Prof. Alan Perkins (Nottingham, UK), Prof. Jean Francois Chatal (Nantes, France), Prof. Angelika Bischof-Delaloye (Lausanne, Switzerland), Prof. Richard Baum (Bad Berka, Germany). Other groups later joined the Society.
At present, IRIST has more than 350 members from all over the world.

Different Presidents leaded IRIST from its origin, among them Drs. Patrick Bourget, Richard Baum, Angelika Bischof-Delaloye, Alan Perkins, Frans Corstens, Thomas Behr and Marion De Jong. In 2002 President Alberto Signore (together with John Buscombe and Christophe van de Wiele) re-organized the society and gave to IRIST a full legal status with the official recognition of a non-profit society for medical research.

Subsequently, John Buscombe, Christophe van de Wiele, Alicja Hubalewska-Dydejczk, Richard Baum, John Prior and Luz Kelly Anzola Fuentes (current) have been Presidents of the society and organizers of congresses.
Almost every two year the IRIST organizes a scientific symposium. The last one, the 23rd, in 2016 took place in May, 2016, in Lausanne, Switzerland.

Invited speakers gave excellent lectures on basic research, dosimetry and therapy of lymphoma, neuroendocrine tumours (NET), thyroid cancer, prostate cancer, and pancreatic cancer. An important part of the congress was devoted to diagnostic imaging with radiolabelled antibodies and peptides in the field of oncology.
